Друзья ни как не пойму как делать

“What is happening to our young people? They disrespect their elders; they disobey their parents. They ignore the law. They riot in the streets, inflamed with wild notions.Their morals are decaying. What is to become of them?” Plato 4th Century!!  (цитата)

What kind of problems do teenagers have nowadays?
Young people can meet difficulties everywhere: at home, at school, in the street. They face to different problems. They are  as school problems, emotional problems, health problems, at home with parents ,     misunderstanding  ,  smoking  ,    using drugs   ,   using alcohol drinks  ,    relationships with lovers.  The teenager is kind enough. Someone  tries to get  good education  nowadays.
Someone is sure that the most important thing in life is health, freedom and the ability to adapt.
Someone  go in for different kinds of sport.  Someone enjoy drugs, alcohol, and smoking. Someone try to make the around world better.
I think that  youth is a very important period in the life of man. This is the time when a  youth  tries to determine  themsel fplace in this world.
Young people of today do not directly accept the standards of their parents who believe that they are right because they are older. so the young and adult do not understand one another. All these things generate a generation gap.
As a kind of protest against the values and lifestyles of the older people informal groups appeared. For example  such as Hippies, Rockers, Bikers, Skinheads, Punks, Goths
I believe  a great future is reserved for Modern Youth in Russia
